Abstract

An annular seal assembly for forming a seal between two annular surfaces. The seal assembly includes an annular base including a sealing surface. The seal assembly also includes a pair of spaced apart rims extending from the annular base opposite the base sealing surface and in opposite directions, the rims also including sealing surfaces. The base is elastically deformable and the rims are elastically deformable relative to the base to effect a self-energized seal between the two annular surfaces.

Claims

AMENDED CLAIMS received by the International Bureau on 04 August 2009(04.08.2009)WHAT IS CLAIMED IS:
1. An annular seal assembly for forming a seal between two annular surfaces, the seal assembly including: an annular base including a sealing surface; a pair of spaced apart rims extending from the annular base opposite the base sealing surface and in opposite directions, the rims including sealing surfaces; the base being elastically deformable and the rims being elastically deformable relative to the base to effect a self-energized seal between the two annular surfaces.
2. The seal assembly of claim 1, wherein the base sealing surface further includes raised sealing bands including sealing surfaces.
3. The seal assembly of claim 1, wherein the base sealing surface includes base secondary seals,
4. • The seal assembly of claim 1 , further including a pressure relief port located between the rirns and extending through the annular base,
5. The seal assembly of claim 1 , further including annular coil springs between the base and each of the rims and positioned to provide resistive radial force to the compression of the rims toward the base.
6. The seal assembly of claim 1 , wherein the annular base and rims form a single body.
7. The seal assembly of claim 1, whetein the annular base and rims are formed into more than one body.
S. The seal assembly αf claim 1, wherein the annular base and rims are metal
9, The seal assembly of claim 1, further including a rim secondary seal.
10. The seal assembly of claim 9, wherein the rim secondary seal is located between the rims.
11. The seal assembly of claim 9, wherein the rim secondary seal includes a seal on the rim sealing surface.
12. The seal assembly of claim 1, wherein the rims are elastjcally deformable relative to the base to accommodate relative movement between ends of the rims and the base and maintain a seal between annular surfaces under dynamic conditions.
13. An annular seal assembly for forming a seal between two annular surfaces, the seal assembly including: an annular base including a sealing surface; a rim extending and from the annular base opposite the base sealing surface and including a sealing surface; the base being elastically deformable and the rim being elastically deformable relative to the base to effect a self-energized seal between the two annular surfaces.
14. The seal assembly of claim 13, wherein the base sealing surface further includes a raised sealing band including a sealing surface.
15. The seal assembly of claim 13, wherein the base sealing surface includes a base secondary seal.
16. The seal assembly of claim 13, further including an annular coil spring between the base and the rim and positioned to provide resistive radial force to the compression of the rim toward the base.
17. The seal assembly of claim 13, further including more than one base and corresponding rim unit, the units aligned axially such that the rims extend oppositely from each other.
18. The seal assembly of claim 13, wherein the annular base and rim are metal.
19. The seal assembly of claim 13, further including a rim secondary seal on the rim sealing surface.
20. The seal assembly of claim 13, wherein the rim is elastically deformable relative to the base to accommodate relative movement between end of the rim and the base and maintain a seal between annular surfaces under dynamic conditions.
21. A subsea completion assembly for a subsea well, the completion assembly including: a wellhead; a production tree engaged with the wellhead and including a tree annular surface; a tubing hanger landed the production tree and including a tubing hanger annular surface; and an annular seal assembly for forming a seal between the tree and tubing hanger annular surfaces, the seal assembly including: an annular base including a sealing surface; a pair of spaced apart rims extending from the annular base opposite the base sealing surface and in opposite directions, the rims including sealing surfaces; the base being elastically deformable and the rims being elastically deformable relative to the base to effect a self-energized seal between the tree and hanger annular surfaces.
22. The subsea completion assembly of claim 21, wherein the base sealing surface further includes raised sealing bands including sealing surfaces.
23. The subsea completion assembly of claim 21, wherein the base sealing surface includes base secondary seals.
24. The subsea completion assembly of claim 21, further including a pressure relief port located between the rims and extending through the annular base.
25. The subsea completion assembly of claim 21, further including annular coil springs between the base and each of the rims and positioned to provide resistive radial force to the compression of the rims toward the base.
26. The subsea completion assembly of claim 21, wherein the annular base and rims are formed into more than one body,
27. The subsea completion assembly of claim 21, wherein the annular base and rims are metal,
28. The subsea completion assembly of claim 21, further including a rim secondary seal.
29. The subsea completion assembly of claim 21, wherein the rims are elastically deformable relative to the base to accommodate relative movement between ends of the rims and the base and maintain a seal between tree and hanger annular surfaces under dynamic conditions.
30. A method of forming an annular seal between first and second annular surfaces, the method including: forming a seal between the first annular surface and an annular seal assembly by deforming the annular seal assembly around the first annular surface; forming a seal between the annular seal assembly and the second annular surface by elastically deforming two rims of the annular seal assembly; and the seals being self-energized annular seals between the first and second annular surfaces due to the deformation of the annular seal assembly,
